Random (minimal) performance improvements at startup. lisp/ChangeLog addition: 2009-09-06 Aidan Kehoe <kehoea@parhasard.net> * simple.el (handle-pre-motion-command-current-command-is-motion): If KEY is a character, ascertain that once, not every iteration of the loop. * mule/mule-cmds.el (finish-set-language-environment): Don't call #'string-match on a one-character string, use functions that have bytecodes instead, since this is called so often on startup.
